Krikri::DeprecationHint

The one-time "[WARNING]: Deprecation warnings can be disabled by setting deprecation_warnings=False in ansible.cfg." hint ansible-core's Display prints ahead of the FIRST deprecation of any kind in a run (Display._deprecated's warning() call is itself deduped process-wide) - shared by every deprecation emitter (parse-time action-mapping warnings, the executor's conditional-delimiter warnings) so the hint appears exactly once across all kinds, not once per emitter.
